To all whom it ma concern:

Be it known t at I, QLARENCE C. Cox.- LETTE, a citizen of the UnitedStates, and a resident of Amsterdam, in the county of [Montgomery andState of New York have made an Invention Appertaining to a Taper Clip,which invention is fully set forth in the following specification.

' My invention has for its ob ect to provide a clip for securing aplurality of sheets together, the clip being formed of a single piece ofwire having two portions that are, by the elasticity of the wire, firmlyheld against each other or in substantially the same plane. The portionsmay be coiled or they may be made U-shaped, according to th forms ofclips well known in the art. The invention consists face havingprojecting parallel ridges or teeth extending transversely to the clipor to the wire from which the clips are formed and disposed more or lessclosely to each other to form a relatively large engaging area, theparallel ridges however being disposed sufliciently apart to enable goodfrictional engagement and not raised sufficiently to cause distinctpenetration of the surface of'the paper. The ridges may be disposed somelittle distance apart, the parallel rela- 80 tion of the slightly raisedridges preventing distinct penetration but affording theproperengagement over a relatively wide area to make the clipexceedingly valuable forgeneral commercial use. 3! so called by reasonof the parallel arrangement of the ridges, is located on portions of theclips that make contact with the sheets which they are designed to hold.The ridges may be formed by sharp parallel transverse 40 cuts of shallowdepth across the wire of the clip before or after the clip is formed orby other suitable means that will strike up the ridges. The file-likesurface forms an engaging surface which will not destroy the surface ofthe sheets that may be held by the clip when they are removed from theclip, but nevertheless the clip will firmly hold the paper. r

An embodiment of the invention is illustrated in the enclosed drawing.

. view of a clip containing the invention. Fig.

2 illustrates an edge view, and Fig. 3 illustrates an enlarged brokenview.

In the form of the clip shown, the clip 1 is provided with 'two U-shapedportions 2 and 3 constituting legs of the clip that are located in thesame plane and consequently one of the U-shaped legs, such as the leg 2,1s located within the other,'that is, the leg 3. The opposite sides'ofthe cli as formed are provided with file-like sur aces. The filelikesurfaces are formed over the sides of the wire that form the oppositefaces of the clip. The file-like surfaces are formed by a plurality ofclosely positioned cross-cuts in the same manner that a flat file isformed. In the preferred form of the invention the file-like surface 4extends from points 5 located above the bends that form the U- shapedportions of the clip to near the ends 6 of the wire, whereby the clipcan be easily started over the paper to which it is to be attached.

In this form of clip when the paper is inserted between the U-shapedlegs in the manner well known the file-like surfaces of oppositesides ofthe clip engage the sheets of paper,-that is, the file-likesurface onone U-shaped leg engages the papers on one side, while the file-likesurfaces of the opposite face of the clip on the other leg engages theother side of the papers. I claim:

1. A paper clipformed of a single piece of wire having bent leg,portions located substantially in the same plane and having file-likesurfaces formed on opposite. faces of the clip.

2. A paper cli formed of a single piece of wire having ll-shaped legportions located substantially in the same plane and having file-likesurfaces formed on opposite faces of the clip and extendin from a pointwell above the curved part 0 the U-shaped portions in order that theclip may be readily started over the edges of the sheet material to beheld by the cli In testimony whereo I have hereunto signed my name tothis specification.

CLARENCE o. GOLLETTE.
